Lucy attended the United States Military Academy at West Point (where she earned a Bachelor of Science degree and a commission in the United States Army as a 2nd Lieutenant) and then Harvard University, where she completed a J.D./M.B.A. She then went to work for the Army's Judge Advocate General's Corps as a trial counsel (prosecutor). In addition, she also served as a legal attaché on her father's staff. In 2015, Lucy held the rank of Major.
Seeking out James
Lucy went to National City to visit James Olsen, arriving at CatCo Worldwide Media to see him. While in his office, she encountered Kara Danvers for the first time, asking James out to dinner to talk after the latter left, as she didn't like the way she and James had left things in Metropolis.
After spending some time with James (during which the two of them rekindled their relationship), Lucy resigned her commission in the Army. She was subsequently hired by Cat Grant as CatCo Worldwide Media's general counsel.
Head of D.E.O.
Lucy resigned from CatCo not long after breaking up with James and returned to the JAG Corps. Her first billet after her return was as legal adviser to Colonel Jim Harper, who was brought in to get to the bottom of the J'onn J'onzz infiltration of the D.E.O. The two interrogated J'onn, who was still in the form of Hank Henshaw, about how he managed to get into the agency.
Like Harper, Lucy is skeptical of J'onn's claim that he actually tried to save Jeremiah Danvers' life. She also believes that J'onn is a potential threat, his claims to have helped save the country from alien threats notwithstanding. They next question Alex. Even though Alex passes a polygraph test, Lucy suspects Alex is hiding something and orders her arrested and hauled to Project Cadmus along with J'onn.
Desperate to save her sister's life, Kara has James summon Lucy to a meeting at Kara's loft. Kara reveals that she is Supergirl - something Lucy suspected all along. Lucy doesn't understand why aliens like Kara and J'onn have to lie, but Kara explains that they are doing so because they are willing to give up everything just to fit in on their new world. She persuades Lucy to help rescue J'onn and Alex. They intercept a truck taking J'onn and Alex to Project Cadmus; Lucy shoots out the truck's tires. When Lucy and Kara return to the D.E.O., they are surprised to discover that Harper has resigned - and, at his insistence, Lucy has been named acting director.
- Unlike her DC comic book counterpart, the show's version of Lucy and her sister Lois do not get along at all.

- Lucy's military awards and decorations include the Meritorious Service Medal, Joint Service Commendation Medal, two Army Commendation Medals, Army Achievement Medal, and various unit, campaign, and service awards, in addition to the Army Staff Identification Badge.
- Lucy Lane first appeared in Superman's Pal, Jimmy Olsen #36 (1959), created by Otto Binder and Curt Swan, as the younger sister of Lois Lane. At some point, Lucy assumed the identity of Superwoman using a costume with a containment field that simulated Kryptonian powers.
